General aspects and recent progress of laser isotope separation are introduced. From the veiwpoint of tunable laser application, emphasis is placed on the spectroscopic characteristics of isotope-selective photochemical reactions for both atomic (AVLIS) and molecular (MLIS) processes with examples of U, Pd, CHF3, and UF6. Potentials of newly developed lasers such as Ti: Al2O3 and FEL are also discussed.
